This capability was required for Gremlin versions older than 2.18.2, because we would inherit the default capabilities of the container runtime, which sometimes included `CAP_NET_RAW`. Incidentally, we've depended on `CAP_NET_RAW` since [2.40.1][1] for another purpose: dependency discovery (when `gremlin.collect.dns=true`). Update the description for when and why this capability is needed. [1]: https://www.gremlin.com/docs/release-notes-linux#2-40-1

This capability was required for Gremlin versions older than 2.18.2, because our
runcdrivers would run sidecars with a "capabilities-add" request that was unaccompanied by a "drop-all" request andCAP_NET_RAWwas among those requested by default.Incidentally, we've depended on
CAP_NET_RAWsince 2.40.1 for another purpose: dependency discovery (whengremlin.collect.dns=true). Update the description for when and why this capability is needed.
